OIL BURNER FOR COOK STOVES AND THE LIKE.

Application, led August 7, 1924.' Serial No. 730,696.

T0 all Lo/om t may concern.'

Be it known that I, PERRY J. SNowDnN, a citizen of the United States,and a resident of Indianapolis, county of Marion, and State of Indiana,have invented a certain new and useful Oil Burner for Cook Stoves andthe like; and I do hereby declare that the following is a full,` clear,and exa-ct dscription thereof, reference being had to the accompanyingdrawings, v in which like numerals refer to like parts.

This invention relates to a fuel oil burner adapted to burn kerosene andthe like.

The chief object of the invention is to construct a burner of thecharacter described which is suitable for stove use, particularlyheating stoves and cookstoves, etc.

The chief feature of the invention consists in the super-positioning ofthe several parts constituting the burner and the gravity flow of vaporproduced in said burner into meeting engagement with the rising aircurrents supplied to the burner, which produces a peripherallysurrounding frame r for heating purposes including vaporizing the fuel.

'Another feature of the invention consists in the provision of aplurality of superposed vaporizing chambers having restrictedcommunication with each other and the lowcrmost chamber discharginglaterally the vaporized fuel from a well and beneath the chamber ininnnediate communication therewith.

Another feature of the `invention consists in the provision of anannular air supply which includes a plurality of coverid tubularportions separated by intermediate portions.V said tubular portionsvhaving a substantially free and laterally and inwardly dischargingaperture and 'said connecting portions having a perforated cover fordischarging air upwardly and outwardly into meeting engagement withlateral discharged fuel in vapor form which'is discharged transverselyof the first mentioned air supply. f u f i rPhe full naturev oftheinvention will be understood vfrom lthe accompanying 'drawings Vand thefollowing description l and claims-zv -f v, L f

In the drawings Fig. 1 is a top planview of, the invention.; l Figi 2isa transverse.: centrat Sectional view; taken ou Aline f Fig. 1 and inthe direction of the arrows.

In the drawings 11 indicates a peripherally and lrrein circular outlinedbase member including an inwardly extending flange 12. Projectingupwardly from said flange 12v is a peripherally outlined flange 13 whichmay or rmay not be similar to the outline of the portion 11. A centralaperture 14.` is provided and the wall 15 thereof constitutes a supportledge for thev suitably outlined air supply member or sccondary base.Said base includes an outer wall 16 and an inner wall 17. Connectingsaid walls are the radially positioned walls 1S arranged in spacedrelation to form tubular portions indicated at 19, which discharge,'-inwardly and laterally through openings 20.

The top 21 forms a supporting portion which, however, is 'separated fromthe adjacent supports and similar supporting portions by an air gap.This air gapy is formed by the cover portion 23 having the air ports 22therein which cover connection is adjacent radial walls 18. Airv in theperipherally outlined channel formed by the outer and inner'walls, 16and 17 respectively, thus is discharged upwardly and outwardly from theperforated cover 23 and inwardly and laterally through ythe outlets 2Oof the v tubular constructions.

l The inner wall 17 at its lower end is extended inwardly,V and upwardlyand terminates in a central hollow support Q4 connected to said wall bythe yintermediate portion 25. The central support lfis adapted toreceive the tubular portion 26 which is externally threaded at 27 toreceive a nut 28 for drawing ,together the remainder of" the casingconnected with said tubular portion 26 so thatit rests as indicated at29 upon the cover portions 21. Plate portion 30 fonms a lower wall ofthe chamber through which the` hollow stem 31 extends.

,Thev top of said chamber is formed by a separating plateor .partition32 integral with said stem. Depending from said bot! tom: plate 30 isawell 33 which includesa Vdepending skirt portion 34 that encirclesthe-tubular portion 26 adjacentthe outlets 'The 'hollow steni`31- isthreadedas at 36 vand* fuel is supplied tosaid tubularstem 31throughqsuitable rneanslO 'au thread..-

ed engagement withfsaid stem."l The air whichpasses up Vbetween thewalls of the hollow support 26 and the fuel supply line dischargeslaterally and outwardlythrough the ports 35 and is deflected downwardlyby the skirt 34 before passing upwardly and outwardly into meetingengagementl jacent the skirt 37. It will thus be apparent that the airwhich is supplied through the ports 2O divides upon the inner wall of a.channel defined by the well Staand passes laterally along said wall andcreates' suc tion upon theports 38 for the drawing of v aporizedfuel`therethrough and into intimate mixture. This vvaporized mixture isdeflected upwardly and outwardly by air discharged by ports 35 andports2:2.V l

rllhe stem 3 1 carries a fuel supplying and distributing spider 40. `Theends ofthe spider arms discharge into a peripheral ring or vfuelreceivingv groove 41. The fuel re` ceived thereby discharges over theedge thereof and impinges upon the upper face of the partition 32 and isdeflected thereby .toward the outer wall. l2 which herein is showninclined inwardly and downwardly. linmediately beneath the parti-tionSQand adjacent the downwardly extendingv edge 43 thereof is a nestinggroove all. Surrounding the well 3B is a rim or projection The fueldischarged into the .groove 44 forms a partial seal and excess liquidfuel discharges into the chamber therebeneath and is trapped by the riml5 and retained until vaporized by the flames engaging that portion ofthe base 30 and the adjacentV portion ofthe side wall A curved or domeshaped cover i-6 suitably secured as by. the bolt andnut construction i7to theseouring flange 4 8 formed 42 and @D the 'upper dafthereef Alsoassociated with the inclined wall and integral with the inclinedvaporizing wall substantially surrounding the same is a Plate iailtrv 49Wliieh iS Prende@ with' e depending flange 50 that includes suitable yadapted 'adjacent o1 .top 'por suitablyuapertured'as at 52 and thepurpose his' lshirt -or ,ring` :formed member `to "S, cada j unetion theincline'dfwaell 42 with'substafntial uni-y formity rather than inspotted or localized relation which would be the case were it not forthe addition of this skirted construction yQCS-51 inclusive.

In communication withr the channel 55 formed by the intermediate portion25, the inner wall'l, andthe bearing 24, is a discharge conduit or pipe56 that pro-jects be yond the wall 13 and is adapted to discharge eXcessfuel into the trough 57 formed by thel three wall portions,11, 12 and13. lThis insures starting of' the burner since when the fuel issupplied to the tubular stem or standard 81 it firstdiscliarges asliquid fuel through the ports 38 into chamber 55 and thence through thepipe 56 to the ring 57.- lIgnition of the fuel iii-this ring serves toheat not'only the incoming' an' discharged through Ythe tubes 19 butfalso serves to heat the? inclinedl wall Li2 ofthe in teriorcfnstructionand vinthis way initial vaporizationof the fuel isvsecured. Thereafterthe vaporif/jatio'n is automatic and continuous.
